99.01    PURPOSE. The purpose of this chapter is to collect from all users of the City sewer system the cost in whole or in part of constructing, maintaining and operating the main sewers and wastewater treatment facilities in proportion to the service provided to each user.

99.02    SEWER SERVICE CHARGES REQUIRED. Every customer shall pay to the City sewer service fees as hereinafter provided. The volume of flow used for computing sewer service charges shall be the metered water consumption of the person as shown in the records of meter readings. Devices for measuring the volume of waste discharged may be required by the Superintendent if this volume cannot otherwise be determined from the metered water consumption records. Metering devices for determining the volume of waste shall be installed, owned and maintained by the person discharging the wastewater. Following approval and installation, such meters may not be removed without the consent of the Superintendent. (Code of Iowa, Sec. 384.84)

99.03    RATE. Each customer shall pay sewer service charges for the use of and for the service supplied by the municipal sanitary sewer system as follows:

  1. First 2,000 gallons or lesser amount per monthly billing period – $21.92.

  2. All over 2,000 gallons per monthly billing period – $2.55 per 1,000 gallons.

  3. In no case shall the minimum service charge be less than $21.92 per monthly billing period, which is necessary to retire the indebtedness, operating and maintenance, and reserve necessary for maintaining the sanitary sewer facility.

  4. All gallonage classifications in the above rate schedule include a constant rate of $2.55 per 1,000 gallons of usage for operation, maintenance and replacement costs.

  5. Customers of the sanitary sewer facility who are not also customers of the municipal water system shall install a meter to calculate sewer usage.

  6. Customers who reside outside the City shall pay an additional charge of $6.70 per monthly billing period.

  7. Each customer shall pay the monthly sewer service charges even when the property is vacant.

  8. Service to industrial establishments may be by contract if the City deems this to be in its best interest. The conditions of the contract must maintain that the industrial establishment pays for its proportionate share of operation and maintenance and replacement costs based on wastewater flows and loading.

Effective for the monthly billing of July 1, 2012, and on each successive July 1st billing thereafter, the billing for said base minimum charge shall be increased automatically by three percent (3%).

99.04    PAYMENT OF BILLS. All sewer service charges are due and payable under the same terms and conditions provided for payment of a combined service account as contained in Section 92.07 of this Code of Ordinances. Sewer service may be discontinued in accordance with the provisions contained in Section 92.08 if the combined service account becomes delinquent, and the provisions contained in Section 92.11 relating to lien notices shall also apply in the event of a delinquent account.

99.05    LIEN FOR NONPAYMENT. Except as provided for in Section 92.10 of this Code of Ordinances, the owner of the premises served and any lessee or tenant thereof shall be jointly and severally liable for sewer service charges to the premises. Sewer service charges remaining unpaid and delinquent shall constitute a lien upon the premises served and shall be certified by the Clerk to the County Treasurer for collection in the same manner as property taxes. (Code of Iowa, Sec. 384.84)

99.06    ANNUAL NOTIFICATION. The City will notify each customer at least annually in conjunction with a regular bill of the rate and that portion of the sewer service charges which is attributable to operation, maintenance and replacement costs of the treatment works.

99.07    METHOD OF COMPUTING CHARGES. The method for computing the minimum charge and the flow charge shall be in accordance with the following formula:

Flow Charge (FC) =

Minimum Charge =

Where: F = Total Annual Revenues Required for Flow Charge

M = Total Annual Revenues Required for Minimum Charge

W = Total Metered Water Usage for Fiscal Year

FC = Flow Charge in $______/1,000 gallons

U = Number of Sewer Users

99.08    BIENNIAL AUDIT. The City shall review, at least every two (2) years, the wastewater contribution of its sewer users, the operation and maintenance expenses of the wastewater treatment facilities, and the sewer service charge system. Based on this review, the City shall revise the sewer service charge system, if necessary, to accomplish the following:

  1. Maintain a proportionate distribution of operation and maintenance expenses among sewer users based on the wastewater volume and pollutant loadings discharged by the users;

  2. Generate sufficient revenues to pay the operation and maintenance expenses of the wastewater treatment facilities; and

  3. Apply excess revenues collected from a class of users to the operation and maintenance expenses attributable to that class of users for the next year and adjust the sewer service charge rates accordingly.

99.09    RECORDS. The City shall maintain records regarding wastewater flows and loadings, costs of the wastewater treatment facilities, sampling programs and other information which is necessary to document compliance with 40 CFR 35, Subpart E of the Clean Water Act.


1. Customers are liable for sewer service charges unless the sewer connection has been capped in accordance with this section.

2. Property owners may, at their expense cap the sewer either at one foot above the ground, at the curb or if a modular/mobile home directly under the house. Televising of the line may be required at the discretion of the Superintendent and the cost shall be the responsibility of the homeowner. All capped lines must be inspected by the Superintendent before approved. (Ord. 118 – Jan. 15 Supp.)
